Question

I’ve an array like this one:

    const int dim = 1000;
    double[,] array = new double[dim, dim];

    Random ran = new Random();
    for (int r = 0; r < dim; r++)
        for (int c = 0; c < dim; c++)
            array[r, c] = (ran.Next(dim));

    DataTable dataTable = new DataTable();

Can I fill the dataTable with the array data?

Answer 1

Try something like this:

var dt = new DataTable();
//AddColumns
for (int c = 0; c < dim; c++)
    dt.Columns.Add(c.ToString(), typeof(double));
//LoadData
for (int r = 0; r < dim; r++)
    dt.LoadDataRow(arry[r]);
